The availability of rich ?rm-level data has led researchers to uncover new evidence on the effects of trade liberalization. First, trade openness forces the least productive fi?rms to exit the market; secondly, it induces surviving fi?rms to increase their innovation efforts; thirdly, it...

We analyze recent contributions to growth theory based on the model of expanding variety of Romer [Romer, P. (1990). “Endogenous technological change”. Journal of Political Economy 98, 71–102]. In the first part, we present different versions of the benchmark linear model with imperfect...

We study the gains from trade in a model with oligopolistic competition, heterogeneous firms and innovation, and provide a formula to decompose the mechanism. The new insight we provide is that market concentration can be a welfare-relevant feature of market power above and beyond markup...

We study the gains from trade in an economy with oligopolistic competition, firm heterogeneity, and innovation. Oligopolistic competition together with free entry make markups responsive to firm productivity and trade costs. Lowering trade costs reduces markups on domestic sales but increases...

This paper studies the effect of competition on firm innovation by developing a discrete-time endogenous growth model where multi-product firms do two types of innovation subject to friction in technology spillovers. Firms improve their existing products through internal innovation while...

We provide a unified framework for quantifying the cross-country and cross-sector interactions among trade, innovation, and knowledge diffusion. We study the effect of trade liberalization in an endogenous growth model in which comparative advantage and the stock of knowledge are determined by...

Productivity differences across countries determine patterns of international trade—hence, comparative advantage. We use a multi-industry model of international trade to estimate a measure of industry productivity. We then quantify the effect that domestic innovation and technology...

This paper studies a model of the distribution of income under bounded needs. Utility derived from any given good reaches a bliss point at a finite consumption level of that good. On the other hand, introducing new varieties always increases utility. It is assumed that each variety is owned by a...
